“…Wildlife population declines are impacting both macro-and micronutrient nutrition for many populations, whereas climate change is expected to reduce the iron, zinc, and protein content of grains that are a critical source of these nutrients for large segments of the human population (94)(95)(96)(97). In combination, iron and zinc deficiency have been estimated by the World Health Organization to cause 63 million life-years to be lost annually (98,99).…”

Human activity is rapidly transforming most of Earth's natural systems. How this transformation is impacting human health, whose health is at greatest risk, and the magnitude of the associated disease burden are relatively new subjects within the field of environmental health. We discuss what is known about the human health implications of changes in the structure and function of natural systems and propose that these changes are affecting human health in a variety of important ways. We identify several gaps and limitations in the research that has been done to date and propose a more systematic and comprehensive approach to applied research in this field. Such efforts could lead to a more robust understanding of the human health impacts of accelerating environmental change and inform decision making in the land-use planning, environmental conservation, and public health policy realms.At least since Hippocrates wrote On Airs, Waters, and Places, the natural environment has been viewed as an important determinant of human health. However, over the last century, the field of environmental health has focused increasingly on quantifying exposure-response relationships for toxins encountered in the human-dominated environment: from an initial focus on workplace exposures, to a population-level focus on radiation, heavy metals, air and water pollution, and more recently, to exposure to endocrinedisrupting chemicals. Over this period, relatively little attention has been paid to how changes in the structure and function of Earth's natural systems might affect human health. Growing evidence that changes in these natural systems can affect human health in a variety of important ways and the increasing pace and extent of these changes has prompted this Perspective. In it, we review current understanding of this field, identify some of its gaps and limitations, and suggest an approach to expanding our understanding.Human activity is transforming nearly all of Earth's natural systems. With the human population now exceeding 7 billion people and rapid growth in per capita consumption of goods and services, humanity's growing ecological footprint is altering the planet's land cover, rivers and oceans, climate system, biogeochemical cycles, and the

“…A similar study by Kersebaum and Nendel (2014), also for winter wheat and varying sites in Germany, using the same climate model and scenario as the presented study, reported yield decreases by -11.6% if the effect was neglected and depending on the algorithm (three tested in total), 0.9 to 6.0% yield increases if the [CO 2 ] effect was included. Apart from this, several articles exist that deal with [CO 2 ] and crop yields on different scales and approaches (Ziska and Bunce, 2007;Högy and Fangmeier, 2008;Soussana et al, 2010;Vanuytrecht et al, 2011;Weigel and Manderscheid, 2012;Tausz et al, 2013;Wang et al, 2013).…”

The quality and quantity of the influence that atmospheric CO 2 has on crop growth is still a matter of debate. This study's aim is to estimate if [CO 2 ] will have an effect on biomass yields at all, to quantify and spatially locate the effects and to explore if an elevated photosynthesis rate or water-use-efficiency is predominantly responsible. This study uses a numerical carbon-based crop model (BioSTAR) to estimate biomass yields within the administrative boundaries of Niedersachsen in Northern Germany. Ten crops are included (winter grains: wheat, barley, rye, triticale-early, medium, late maize variety-sunflower, sorghum, spring wheat), modeled annually for the entire twenty-first century on 91,014 separate sites. Modeling was conducted twice, once with an annually adapted [CO 2 ] concentration according to the SRES-A1B scenario and once with a fixed concentration of 390 ppm to separate the influence of [CO 2 ] from that of the other input variables. Rising [CO 2 ] concentrations will play a central role in keeping future yields of all crops above or around today's level. Differences in yields between modeling with fixed or adapted [CO 2 ] can be as high as 60% toward the century's end. Generally, yields will increase when [CO 2 ] rises and decline when it is kept constant. As C 4 -crops are equivalently affected it is presumed that an elevated efficiency in water use is the main responsible factor for all plants.

Abstract-Plant species depend on specific environment conditions to optimum growing. There are various agricultural areas that comprised from plant species which originated in climatically quite different regions. Plants absorb many elements from soil which have biological function and some of them are known as toxic also at low amounts. In case of environmental conditions change, plants will response as changing some of their metabolic activities. So that some of the quality parameters will change. Some of the plants can adopt as well as reasonable values, but some of them will be affected negatively. Although human are not able to or has limits to change ecological situations, they also able to recognize some characteristics of plants and again can develop new plant species and regulate or eliminate some of the harmful effects of environment on plant quality parameters for adaptation to different climatic conditions. If we know the effects of ecological conditions on plants, the definition and improvement of plant quality parameters will be easy. Therefore plants are the basic place of food chain; there are some sorrows about their quality and credibility.Index Terms-Environment, food quality, human nutrition, inhibitors.
